【Abstract】 Disadvantages of classical theory of cell nucleation in motion polymer melt were analyzed. The research development of cell nucleation in shear flow field was introduced, and the disadvantages of cell stretch model and cavity nucleation model in shear flow field to explain cell nucleation were analyzed and discussed in detail. The lastest shear energy nucleation theory during cell nucleation was recommended, which explained the process of cell nucleation in shear flow field perfectly. Finally, the development trend of cell nucleation was pointed out.更多还原
